4.3 ElectricalConnections
compact piezo LED allows various electrical
congurationstosatisfythecharacteristicsof
the dental unit in which it is housed.
The dental units to which the
compact piezo LED device can be connected
must be able to provide one of the following
power supplies:
• 24V~50/60Hzor
• 32 V
with minimum power 40VA.
Moreover, it must have a 2A, 250V safety fuse.
Fortheelectricalconnections,the
compact piezo LED device is equipped with 2
connectors (see Figure3apagina13 ):
• M1 : connector with 2x8 contacts for the
module controls;
• M2 : connector with 2 contacts for
connection of the handpiece cable
(piezoelectricelementscontrol);
• M3 : connector with 2 contacts for
